I think that's not really the output impedance but the load impedance. The output impedance is a few milliohms IIRC.

Here's the datasheet of the PS170 power amp, you can check by yourself an you'll also find the circuit diagram and a few graphs:

Thanks for that, I appreciate it. Yes, I understand that I was talking about the load impedance spec. But that's my question, considering that the output impedance spec is so low (as expected) and the output current is unlimited as per the data sheet, what is the problem say with a 2 Ohm load? Is it just a thermal issue?
